The images of the meniscus of the mercury column and of the moving fork are focused on the plate by a lens.
Sometimes, as in the Ornithorhynchus, the meniscus is absent.
A correction must be introduced for the error caused by the meniscus of the mercury.
In order to obtain an accurate result, the meniscus should be removed.
The height of the meniscus is then read on a millimetre scale attached to the capillary.
With most instruments the reading is taken from the bottom of the meniscus.
Spherical aberration is overcome to a great extent by the use (in connection with the double convex) of a meniscus lens.
The temperature of the thermostat is then raised degree by degree, and the height of the meniscus at each point ascertained.
A meniscus, so called from its resembling the crescent moon.
The addition of a few drops of potash solution destroys the meniscus, and allows of a close reading of the volume.
"crescent-shaped body," 1690s in reference to lenses, c.1812 in reference to liquid surfaces, Modern Latin meniscus, from Greek meniskos "lunar crescent," diminutive of mene "moon" (see moon (n.)). Related: Meniscoid.
